Given , v = 3.60 m/s
            P=  180 kg m/s 
we know that P = mv
                     180 = m × 3.60
                        m = 180/3.60
                        m = 50 Kg
the mass of body is 50 Kg.

To solve the problem we must know the concept of momentum.

What is Momentum?

Momentum is defined as the product of the mass of an object and the velocity of an object. It is a vector quantity.

[tex]\rm{Momentum = velocity \times Mass[/tex]

The mass of the object is 50 kg.

Given to us

  • velocity of the object = 3.60 m/s
  • momentum of the object = 180 kg m/s

Mass of the object

We know that momentum is the product of the mass of the object and the velocity of the object,

[tex]\rm{Momentum = velocity \times Mass[/tex]

Substitute the values,

[tex]180 = 3.60 \times \rm Mass[/tex]

[tex]\rm Mass = \dfrac{180\ kg\ m/s}{3.6\ m/s}[/tex]

[tex]\rm Mass = 50\ kg[/tex]

Hence, the mass of the object is 50 kg.
